Hellions by Zeb Wells. Vol. 2

"Mr. Sinister’s team of Hellions are dead! When the team is restored on Krakoa, why do they feel a bit — different? Then: it sounded like a simple mission. Retrieve Nanny’s ship and create a new containment armor for the recently resurrected Orphan-Maker. But the emergence of an old enemy and his deadly warriors are about to make the Hellions’ new lives a hell on Earth! And when Mr. Sinister vanishes, will the Hellions be able to put aside the tensions poised to split the team apart long enough to unravel the mystery? The fallout from X OF SWORDS continues here—and it’s huge!"--Goodreads.com
